Flares from ultra-magnetized neutron stars, or magnetars, may be key contributors to the universe’s supply of heavy elements like gold and platinum, according to a new study from Ohio State University.

Astrophysicists have studied a cosmic event that took place 8.5 billion light-years away, where two neutron stars collided, producing a short gamma-ray burst known as GRB 230906A. These binary neutron star mergers are among the most powerful explosions in the universe, releasing immense energy and creating heavy elements such as gold and platinum. The researchers used NASA's Chandra X-ray Observatory, the Hubble Space Telescope, and the Very Large Telescope in Chile to locate the explosion in a faint dwarf galaxy formed from material stripped away during a galaxy collision. This is the first time a neutron star merger has been linked to such a tidal environment, showing that these collisions can occur outside massive galaxies. The study sheds light on how heavy metals are distributed across the cosmos and suggests that galactic interactions play a key role in producing environments for these mergers. While the exact elements formed in this specific event remain unknown, upcoming observatories like the James Webb Space Telescope, the Nancy Grace Roman Space Telescope, and next-generation X-ray missions will enable more detailed studies. Future gravitational wave detectors, including the Einstein Telescope and Cosmic Explorer, will complement these observations, marking a new era in multimessenger astronomy and improving our understanding of the origins of elements that make up our world.
